MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented Feb. 27, 1906'.

Application filed August 14, 1905. Serial No. 274,145.

To all whom it may concern.-

Be it known that we, WALTER L. CAY- woon and ERNEST M. STEELE, citizens of the United States, residing at Canon City, in the county of Fremont and State of Colorado, have invented certain new and useful Improvements in Music-Leaf Turners; and we do declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relatesto improvements in music-leaf turners and it consists in certain novel features of construction, combination, and arrangement of parts hereinafter described and claimed.

The object of the invention is to provide a simple and comparatively inexpensive device of this character by which the leaves may be turned in either direction, so that the performer may repeat the music or portions thereof.

A further object of the invention is to improve and simplify the construction and operation of devices of this character, and thereby render the same more efficient and durable in use and less expensive to manufacture.

The above and other objects which will appear as the nature of our invention is better understood are accomplished by means of the construction illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of our improved music-leaf turner. Fig. 2 is a front elevation of the same, showing one of the levers depressed for the purpose of turning one of the leaves forwardly. Fig. 3 is a horizontal sectional View taken on the line 3 3 in Fig. 2. Fig. 4 is a vertical transverse sectional view taken on the line 4 4 in Fig. 3, and Fig. 5 is a perspective view of the cam device for moving the leaf-folding elements.

Referring to the drawings by numeral, 1 denotes a suitable frame upon which the operating parts of the device are mounted and which may be supported upon the usual music-rack of a piano, organ, stand, or the like, or which may be fixedly or detachably clamped or secured thereon in any desired manner. The frame 1, as shown, is of rectangular form and has at the center of its upper and lower bars 2 pivots 3 4, upon which a plurality of music-leaf-holding devices or elements 5 are mounted to swing. These devices 5 are preferably in the form of rectangular frames of wire which have at their two inner corners eyes 6 to receive the pivots 3 4. The music-leaves are adapted to be retained upon the frames 5 by springs 7, which may be soldered or otherwise secured to said frames, as shown.

The mechanism for turning the leaf-hold ing frames or elements 5 is mounted upon the bottom bar 2 and comprises a bracket 8 of substantially U form, which has bearings for the lower pivot 4. The latter is in the form of a vertically-disposed shaft which is loosely mounted in its bearings and has fixed upon it upper and lower cam devices 9 10. These devices are adapted to engage and actuate the frames 5, the lower'cam 10 moving the said frames forwardly, or from right to left, and the upper cam 9 moving them rearwardly, or from left to right. These cam devices are similar in construction, each con sisting of a substantially semicircular-shaped body having at its center a hook 11 and camfaces 12 upon each side of said hook. The lower cam 10 is fixed to the shaft 4, as shown at 13, and the upper cam 9 is pivotallymounted, as shown at 14, upon the ends of a block or head 15, whichis adjustably mounted upon the upper portion of the shaft 4 by means of a set-screw 16. By pivotally mounting the cam 9 in this manner it is permitted to swing or tilt downwardly for a purpose presently explained. The downward movement of the cam is limited by a stop 17, provided upon the block 15 and adapted to engage a projection 18 upon the central portion of the cam 9. The two devices 9 and 10 are oscillated simultaneously in either direction by actuating-levers 20, arranged upon opposite sides of the device, the one upon the right being adapted to move them in one direction, and the one upon the left to move them in the opposite direction. Each of said levers has its outer end pivoted, as at 21, upon the lower bar 2 and its inner end slotted, as shown at 22, to engage a stud 23, provided upon the under side of the lower cam 10. The levers 21 are connected intermediate their ends by links 24 to hand-levers 25 26. are pivoted, as at 27, upon the under side of the bracket 7, so that their outer ends project downwardly and forwardly in opposite directions. These hand-levers are disposed These levers directly in front of the bar 2 and are actuated by springs 28, which, as shown, are in the form of coils which have their inner ends seated in sockets provided in the bar 2 and 5 their outer ends engaging the under sides of the levers 25 26, as shown in Fig. 3.

The operation of the device is as follows: When the parts are in the position shown in Fig. 1 of the drawings and it is desired to turn one of the leaf-holding frames 5, the outer end of the lever 26 is moved inwardly. This movement of the lever will be imparted to the right-hand lever 20, which latter will oscillate the cam devices 9 10, so that the i5 hook of the lower cam 10 will be moved under and into engagement with the uppermost frame 5, as shown in Fig. 2 of the drawings. It will be seen that the cam-face 12 upon the adjacent side of the cam 11 will elevate the frames 5, as the cam is oscillated, until the lowermost frame 5 drops into the hook 11 of said cam 10. As soon as the lever 26 is released the spring will return it to its normal position, and the cam 10 will also be returned,

the same carrying the uppermost frame 5 with it and throwing it over upon the lefthand side of the device. By repeatedly depressing the lever 26 the remaining frames 5 may be successively swung from right to left.

0 hen it is desired to return the frames 5 to the right-hand side of the device, or should it be desired to return any one of them, so that the performer may repeat certain portions of the music upon the sheet held by said frame 3 5 the lever 25 is depressed. When this is done, the cam devices will be oscillated from right to left, so that the hook of the upper cam 9 will engage the uppermost frame 5 to swing the same from left to right. Owing to the 0 pivotal mounting of the cam 9 it will be seen that the same will swing upwardly to permit its hook to drop down in rear of the lower bar of the frame 5 and engage the same.

From the foregoing description, taken in 4 5 connection with the accompanying drawings,

the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion,

and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described our invention, what we claim as new, and desire to secure by Let- 5 5 ters Patent, is-

1. A music-leaf turner comprising swinging,vertically-movable leaf-holders, each having a lower arm, the respective lower arms of the leaf-holders being one above another, a lower cam device, and an upper cam device, respectively below and above the lower arms of the leaf-holders, said cam devices being mounted for simultaneous oscillatory movement in a horizontal plane and said upper cam device being also mounted for independent vertical angular movement, and means to operate said cam devices.

2. A music-leaf turner comprising swinging,vertically-movable leaf-holders, each having a lower arm, a vertical shaft mounted for oscillatory movement, and to which the lower arms of the leaf-holders are connected for vertical and also for independent angular movement in horizontal planes, a lower cam device and an upper cam device respectively below and above the lower arms of the leafholders, said cam devices being connected to and oscillated with the said shaft, and said upper cam device being also mounted for independent angular movement in a vertical plane, and means to simultaneously turn said cam devices in either direction.

3. A music-leaf turner comprising swinging,vertically-movable leaf-holders, each having a lower arm, the respective lower arms of the leaf-holders being one above another, a lower cam device and an upper cam device respectively below and above the lower arms of the leaf-holders, said cam devices being mounted for simultaneous oscillatory movement in a horizontal plane and said upper cam device being also mounted for independent vertical angular movement, levers connected to the lower cam device, hand-levers, links connecting the hand-levers to the firstmentioned levers, and springs pressing the free ends of the hand-levers outwardly, substantially as described.

In testimony whereof we have hereunto I00 I set our hands in presence of two subscribing witnesses.
